Application mea .my 1e, w23. serian no. 651,902.

To all whom it may coment.' Be it known that I, RICHARD EVANS, a citizen of the United States, residing at Highland Park, in the county of Lake and State of Illinois, have invented new and useful Improvements vin Type Matrices, of which the following is a specification.

This invention relates to matricesparticularly designed for use in the makin of rubber type or stamps, and an ob]ect o the invention is to provide matrices which will materially reduce the amount of work contingent with the making of rubber type or stamps and which will conseqlliently reduce the cost of manufacture of suc article.

v Heretofore, it has been the lpractice, in the making of rubber type or ru ber stamps to assemble the printers type, and lock the assembled t pe in a chase from which a mold of a suitable compound is made. After the mold is formed it must be allowed to harden and dry before the rubber type or stamp can be vulcanized therefrom and after the mold is roperly hardened a sheet of unvulcanized rubber is placedl on the mold and the mold is placed in a vulcanizer which is heated to the proper temperature, and pressure applied which forces the rubber into the mold. In a specified time the rubber will become vulcanized after which it is removed from the mold with the result that the rubber will be a facsimile of the type originally used in formin the mold.

An d'bject of the present invention is to provide type matrices for forming the rubber type or stamps which will eliminate the making of the mold, which mold is relatively expensive in that it requires a skilled artisan to make it, besides re uiring the cost of the composition and the delay necessary for allowin the mold to dry.

Other ob]ects of the invehtion will appear in the following detailed description taken in connection with the accompanying drawings wherein r- Fig. 1 is a plan view of one side of a form of type matrices.

Fig. 2 is a face view of the other side of the form of assembled type matrices.

Fig. 3 is a Vertical section taken on the line 3--3 of Fig. l.

Fig. 4 is a perspective View of one bar of type constructed in accordance with this inthe -present invention, in which the type body 1 has an embossed or raised letter or character 2, upon one end and an en aved or sunk letter or character 3, upon t e opposite end which engraved letters, when assembled in word formation, as shown in Fig. 2 of the drawings and properly clamped in a chase 4, of any approved construction,

form the' matrix or moldl from which the rubber type or rubber stam is made. The embossed letter 2 is provi ed -to facilitate the setting of the type matrices, and to permit the takin of proofs from them for the detection an correction of mistakes after the type has been set.- The spaces, quads, leads and slugs together with the type matrices must be of equal height. However, the spaces, quads, leads and slugs being type high preferably have dots as shown at 5 thereon, so that a proof can be taken of the form Without the ends of the quads, spaces, leads and slugs showing up solid which would make a very unsatisfactory print or proof, such solid im ression being eliminated by the dots 5. fter the type is properly assembled, the side opposite that on which the embossed letters, 2, are formed will carry a matrix or depressed representation, 6, of the words, characters, or the like, 7, formed by the letters 2 and it is from this matrix that the rubber type or stamp is made. In making the rubber stamp or type, a sheet of unvulcanized rubber is placed directly on the side of the assembled type matrices-on which the engraved lettersB are formed, and it is then vulcanized and withdrawn in the usual manner, which provides a rubber stamp without requiring the use of the type of molds now commonly employed in the making of rubber stamps and. it also provides that all of the letters in the stamp will always be perfect, owing to the fact that the liability of distorting or disrupting the letters when the mold 1s soft is eliminated.

mold and provide sufficient body for thev rubber stamp. The inner surfaces 10 of the edge portions 8 and 9 are inclined, as clearly shown in Figs. 3 and 4: of the drawings gradually inclinlng outwardly towards their outer ends so as to permit the formed rubber type or stamp to be readily removed.

llt is, of course, to be understood that the invention maybe constructed in other manners and' the parts associated in different relations and, therefore, ll do not desire to be limited in any manner except as set forth in the claims hereunto appended.

Having thus described my invention what l claim is Il. As a new article of manufacture, a `type bar having a character embossed on one end and the same character engraved in the opposite end, said bar having edge portions extended along two sides at the engraved end, one of said extensions being longer than the other.

2. As a new article of manufacture, a type bar having a character embossed on one end and the .same character engraved in the opposite end, said bar having edge portions extended along two sides at the engraved end, said extensions having their inner surfaces inclining outwardly.

3. As a new article of manufacture, a type bar having a character embossed on one end and the same character engraved in the opposite end, said bar having edge portions extended along two sides at the engraved end, one of said extensions being longer than the other, said extensions havlng their inner surfaces inclining outwardly.

d. A matrix for forming rubber type or stamps comprising a p-lurality of type matrices having embossed characters on one end and the same characters engraved in their opposite ends, and a lurality of spacing media havingI flat en surfaces at the engraved end of the character bars, and peiod forming points upon their opposite en s.

5. A matrix for forming rubber type or stamps comprising a plurality oil type period rming points upon their opposite ends, the character carrying bars having' their engraved ends cut away forming extensions at opposite sides one of which extensions lies'dush with the dat surfaces of the spacing media while the other extension has its outer end located inwardly of the tlat end surfaces of the spacing media.

6. A matrix for forming rubber' type or stamps comprising a plurality ot type matrices having embossed characters on one end and the same characters engraved in their opposite ends, a plurality ot' spacing type media having dat end surfaces at the engraved end of the character bars, and period forming points upon their opposite ends, the character vcarrying bars having their engraved ends cut away forming extensions at opposite sides one ot which extensions lies tlush lwith the dat surfaces ofi the s acing media while the other extension has lts outer end located inwardly of the llat end surfaces oir the spacing media, said extensions having their inner sides inclined.

7. As a new article ol manufacture, a type bar having a character engraved in one end thereof, said bar havingedge portions extended along two `sides of said engraved end, and one oit said extensions being longer than the other.

8. Asa new article oit manufacture, a type bar having a character engraved in one end thereof, said bar having edge portions extended along two sides oil said engraved end, and one of said extensions being longer than the other, said extensions having their inner surfaces' inclining inwardly.
